I have gotten 5 different answers to this. Ive read the guidelines on coding excisions but I am confused by this one.
Left shoulder lipoma excision is 2.5 x 1.0 x .5 including circumferential margins.
Right cheek carcinoma 1.0 x 1.0 x.5.
For the first one, I get 2.5 + 1 (biggest diameter plus twice the margins) = 3.5.
However, the answer states it is code 11403-51-LT. But, that code is excised diameter 2.1 a 3.0.
For the right cheek, I did 1.0 + 1 = 2. The code answer says 11641-RT which is excised diameter 0.6 – 1.0.
Is this because Im the main code, it says including margins, so I would not actually add in the margins???
Thank you!!!!
